CHARLES E. DRESSLEIR, OF NEW YORK, N. Y.

GAS-STOVE.

SPECIFICATION forming part of Letters Patent No. 585,815, dated July 6, 1897.

Application filed October 10, 1894.

To all whom it may concern:

Beit known that I, CHARLES E. DRESSLER, of the city of New York, in the county and State of New York, have invented a new and useful Improvement in Gas-Stoves, which invention or improvement is fully set forth and illustrated in the following specification and accompanying drawings.`

The object of this invention is to provide a gas-stove which will effect an efficient and economical radiation of heat with the smallest. forms of stove and in which there shall be a practically perfect consumption of the fuelemployed.

The invention will first be described in detail and then set forth in the claims.

In the accompanying drawings, Figure 1 shows in front elevation a gas-stove embodying my invention. Fig. 2 is a sectional side elevation of Fig. 1. Fig. 3 is a reduced back view of Fig. 1.

In said figures the several parts are respectively indicated by reference numbers and letters, as follows:

The number 1 indicates a base or support composed of two parts a b. Formed integral with the parts a and b, respectively, are front and back plates or shells 2 3, secured together near their tops by a screw or bolt 4. The front plate or shell 2 is provided with a large opening 5, extending from a point near the top of said plate to its bottom and opening into the atmosphere. Within said plate is an angle-iron 6, secured to the part a of the base 1 by means of bolts 7, passing through said angle -iron and base and through webs S, formed on the part b, which webs lap the part a of the base 1. Said bolts thus serve the purpose also of securing the two parts of the base together, but the several parts may be secured together in any other suitable manner.

The back piece 3 of the stove is provided with vertical ribs 9 and a lug or projection 10. Resting against said ribs and secured to said lug by a screw 1l is a vertical bridge piece or plate 127 which may be made of cast-iron, fireclay, or any suitable refractory material. Formed in the lower portion of the back piece 8 is a gas-conduit 13, to one end of which, 14, a gas-pipe from any suitable source may be connected, the other end of said conduit being preferably closed with a removable plug 15.

Serial No. 525,491. (No model.)

It will be seen that by removing and changing the location of the plug 15 the pipe may be connected to whichever end of the conduit may be most convenient.

Connected to the conduit 13 are several ordinary gas-tips 16,.which are partly nclosed within tubes 17 ,eXtendingthrough the bridgepiece 12. Each tube 17 is preferably open at both ends, as shown, and is provided in its sides with openings 18. This arrangement of gas-burner and tube constitutes in effect what is known as a Bunsen burner, and as many of said burners may be employed as the `size of the stove may require.

The operation of this gas-stove is as follows: The supply of gas from the pipe enters the stove through the tip 16 and the tube 17 and is ignited through the opening 5 in the front plate 2. The flame is carried upward in front of the bridge-piece 12, the angle-iron 6 serving to assist in deflectin g said name upward. In heating the air the llame rises in front of the bridge-piece 12 to about its top, where it is extinguished by the current of inrushing air. Said air, having been heated by the flame, is carried downward behind the bridge-piece 12 and is drawn into the Bunsen burners through the openings 18 in the tube 17, carrying with it any gas or carbon which may have remained unburned or unconsumed. The heated air may also enter the tubes 17 through their rear ends 18 (into which extend the tips 16) if said ends be left open. If the apertures 18 be omitted, the air will enter only through said ends 18a. After so entering the Bunsen burners the heated air, containing more or less imperfectly-consumed products of combustion, will be again carried upward through the flame, and thus, with additions of fresh air, be used over and over again until practically perfect combustion is maintained, the flame being consequently kept at its highest temperature as long as this steady circulation of blast continues. The course of circulation of the gasflame""`and heated air is indicated by the arrows, in Fig. 2. The burning gas thus receives, practically automatically, its exact chemical equivalent from the heated air necessary for the nearest approach to practical perfect combustion-namely, the carbureted hydrogen gas is converted into carbonic-acid IOO nails.

The advantages of my invention will be apparent from the above description. As the air after the rst ignition of the gas is heated before entering the Bunsen burners -and isI kept constantly circulating, 'thereby increas ing its heat by degrees, combustion is more perfect than in other gas-stoves noW in useg and radiation of heat is obtained with less consumption of gas. No connection with a chimney is necessary for the vreason that thev carbon contained in the gas is entirely consumed, thus preventing the-existence of those? poisonous odors or fumes Which so frequently attend .the .use of gas-stoves.
